Mungo2007 Posted May 14, 2020 Share Posted May 14, 2020 Hi all i have a 2008 A3 but for some reason the temperature gauge has stopped working any ideas on where to look for the issue the rest of the dash is working ok just the temp gauge not working. Is there a separate fuse just for this gauge, fuses are always my first port of call. Otherwise are there any other things i can test to see where the fault is. Not sure if it is related in anyway but i changed the oil filter and then the temp gauge stopped working i think! I am sure it was working before the filter change might not be related at all but thought i would mention it. Thanks Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted May 14, 2020 Share Posted May 14, 2020 If it happened when you changed the oil filter the chances are that you dislodged the plug on the temperature sender. Quote Link to comment Share on other sites More sharing options...
Mungo2007 Posted May 14, 2020 Author Share Posted May 14, 2020 Yes that is quite possible i did have to push some stuff out of the way to get the filter out - now you have said that when i was putting the filter back in there was what it thought was a static type crack from somewhere close to the filter i did not think any more but now you have said that i wonder, is this connected to a fuse somewhere for this part. Any to ask maybe a silly question what does the temp send plug look like i assume it is near to the oil filter? Quote Link to comment Share on other sites More sharing options...
cliffcoggin Posted May 14, 2020 Share Posted May 14, 2020 Sorry I don't know the location of the sender off hand, as it would depend on the engine, which you haven't mentioned. Often the sender will be fitted into one of the coolant hoses attached to the radiator. In any case there may be a damaged wire or other connection into the loom further out from the sender. You will need to find the sender, ensure the plug is fully seated into its socket, and trace the wires as far back as you can manage. I very much doubt any instrument has a fuse except perhaps on the circuit board in the instrument panel. Quote Link to comment Share on other sites More sharing options...
Steve Q Posted May 15, 2020 Share Posted May 15, 2020 There won't be a separate fuse for the temp sensor. As cliff as mentioned it could be the sensor that's been knocked or failed. But it could also be the temp gauge itself in the instrument cluster. This is a rarer issue and would look at the sensor first. Quote Link to comment Share on other sites More sharing options...
Mungo2007 Posted May 20, 2020 Author Share Posted May 20, 2020 all sorted it was a loose plug gave it a clean and job done easier than i thought it would be 1 Quote Link to comment Share on other sites More sharing options...

diana.mcclendon Posted March 25, 2023 Share Posted March 25, 2023 I have a 2006 audi and my temperature gauge stopped working it stays on C I tried changing the fuse and it worked for a minute but quit again what could it be Quote Link to comment Share on other sites More sharing options...
Magnet Posted March 25, 2023 Share Posted March 25, 2023 Hello? (Could you please fill in your profile with the appropriate data). If the fuse is blowing then there is a short circuit in the circuit to the gauge, or something else on the same circuit. You may be able to locate and sort it yourself if you are competent with car electrics ( complex these days). If not, you will need the services of an auto electrician. Kind regards, Gareth.

Audi_Icarus Posted April 30 Share Posted April 30 I'm actually having a similar issue. First I'll start off by saying its the Audi A3 2008, it's an 8p chassis and 3.2L vr6 motor. So earlier this morning my gauge was working just fine, then randomly went down. It is a pretty cold morning so I was assuming that it was just the cold temp, but I took the long and slow way home and still didn't even go up. After getting home I checked the hoses, they have flow and the hoses are hot. Nothing seems to be out of the ordinary when it comes to the engine running etc. No leaks, I checked the bottom hose where the sensor is(I think that's the sensor anyway) its still in there pretty good. Now when I started checking the gauge to see if it had any movement, I noticed when I turned the key to on the needle goes up such a small amount some wouldn't even notice, like a little spasm. But when the key is turned to off, it goes back down the 1mm if that. Not sure if this is a cluster problem or a fuse problem. Some people were saying check the plug in the engine block and Im lost for words on that cuz not a clue as to where that would be. Any help would be welcomed. Im pretty good with mechanical stuff, not so much electrical which is what I am assuming this issue would be. I believe the engine code is also CBRA if that helps.
